The peak emission from a black body at a certain temperature

The peak emission from a black body at a certain temperature occurs at a wavelength of 6000A On increasing its temperature the total radiation emitted is increased to 16 times These radiations are allowed to fall on a metal surface Photoelectrons emitted by the peak radiation at higher temperature can be bought to rest by applying a potential equivalent to the excitation potential corresponding to the transition for the level n 4 to n 2 in the Bohr s hydrogen atom The work function of the metal is O eV a given by 100 where is the umerical constant The value of is found out to be 3p find the 0
